'Ihis invention relates toV safety hooks and has for its principal object to provide such a hook which may be readily fastened or unfastened, and when fastened or hooked A will be proof against accidental disconnection. Another-object is to provide such a safety hook of simple, durable vand inexpensive constructionjvand one wherein the addition of the safety means does not weaken the hook to which applied.

Other objects of the invention .will appear in the further description thereof. Referring now `to the accompanying draws ing, forming part of this application and vwherein like reference characters indicate like parts: l

Figurey 1 is aside elevation of my improved hook; i

Figure 2 is a side elevation thereof; andv Figure 3 is a vertical central section of the hook.

The main hook is indicated at 1, it being the same as any ordinary hook, the upper 25, end of which is in the form of an eye 2, which may engage a line or chain, or other means with which. the hook may be used.

Upon either side of the hook 1 is a relatively thin sister hook Sf, the upper endY of each of which is pivoted to thel shank of the hook 1 as by the pin or rivet 4: which passes through the shank of the hook adjacent theeye 2. vThe hooks 3 are-almost identical in shape to the' hook 1, and are positioned in opposite relationV so that When closed they inclose a space 5 through` which the element supported passes. At 6 I have shown a rectangularly shaped filler piece which in thicknessV is just equal toy that of i the hook 1 and which is welded or otherwise 40' formed integral with the sister hooksy thereby holding them approximatelyl mid` way their ends spacedapart the required distanceto properly function, or `to-` allow the hook-1 tol freely passtherebetween. It 45` will be noted that the reinforcing or filler block 6 acts as a stop for-the hook 1, or in other words the hooks `cannot close upon veach other closerthan that 'shown in Figure piece 6.

From the foregoing it is apparent that the y hook 1 lmay function in all respects as an i ordinary hook and thatthe addition of the l safety 'sister hooks does not weaken the'hook at all, but addslstrength thereto, and when the hook isclosed about achain link or cable,y and strain applied thereto theI same cannot j free itself from the hookfV i j c j Having thus described myinvention, what v I claim and desire to, secure by Letters Pat? ent, is

In combination, a one; end thereof, a relatively thin sister hook 465 `pivotally mounted adjacent `the eyev upon hook having lan eye in either side of the hook, and integrallyk formed spacing means uniting the sister.y hooks for the purpose described.

In testimony .whereof I hereunto affix HAROLD srooKsrAn signature.
